Developers have been using OpenCV library to develop computer vision applications for a long time. However, they now need a more effective tool to get the job done and in a much better and modern way. Qt is one of the major frameworks available for this task at the moment. This book will teach you to develop applications with the combination of OpenCV 3 and Qt5, and how to create cross-platform computer vision applications. We’ll begin by introducing Qt, its IDE, and its SDK. Next you’ll learn how to use the OpenCV API to integrate both tools, and see how to configure Qt to use OpenCV. You’ll go on to build a full-fledged computer vision application throughout the book. Later, you’ll create a stunning UI application using the Qt widgets technology, where you’ll display the images after they are processed in an efficient way. At the end of the book, you’ll learn how to convert OpenCV Mat to Qt QImage. You’ll also see how to efficiently process images to filter them, transform them, detect or track objects as well as analyze video. You’ll become better at developing OpenCV applications.
Concurrency with Modern C++. What every professional C++ programmer should know about concurrency
Rainer Grimm
C++11 is the first C++ standard that deals with concurrency. The story goes on with C++17 and will continue with C++20/23. Concurrency with Modern C++ is a practical guide that gets you to grips with concurrent programming in Modern C++.Starting with the C++ memory model and using many ready-to-run code examples, the book covers everything you need to improve your C++ multithreading skills. You'll gain insight into different design patterns. You'll also uncover the general consideration you have to keep in mind while designing a concurrent data structure. The final chapter in the book talks extensively about the common pitfalls of concurrent programming and ways to overcome these hurdles.By the end of the book, you'll have the skills to build your own concurrent programs and enhance your knowledge base.

Czysty kod w C++17. Oprogramowanie łatwe w utrzymaniu
Stephan Roth
Wzorce i najlepsze praktyki rozwoju łatwego w utrzymaniu oprogramowania w C++17 Język C++ jest wszechstronnym, potężnym językiem programowania, który ma bardzo różne zastosowania. To klasyczne, wciąż udoskonalane i unowocześniane narzędzie. Problemem jednak jest to, że programiści piszący w C++ dość często mają złe nawyki. Nie przestrzegają zasad manifestu Software Craftsmanship, stosują okropną składnię, całkowicie ignorują podstawowe reguły prawidłowego projektowania i pisania oprogramowania, a tworzony przez nich kod, choć często wydajny i szybki, bywa niemal niemożliwy w utrzymaniu. Jeśli chcesz, aby Twój kod C++ stał się optymalny i zyskał wyższą jakość, powinieneś uważnie przestudiować tę książkę. Pisanie dobrego kodu oznacza przyjemniejszą i wydajniejszą pracę. Niezależnie od tego, czy dopiero zaczynasz przygodę z C++, czy jesteś doświadczonym deweloperem, znajdziesz w tej publikacji cenne i przydatne informacje dotyczące zasad pisania kodu. Akronimy KISS, YAGNI czy DRY zyskają dla Ciebie nowe znaczenie! Otrzymasz też mnóstwo przydatnych wskazówek odnoszących się do pisania funkcji, prowadzenia testów, obsługi wyjątków i błędów, a nawet umieszczania komentarzy w kodzie. Na licznych przykładach pokazano, jak pisać zrozumiały, elastyczny, łatwy w konserwacji i wydajny kod w C++. W książce między innymi: Solidne wyjaśnienie zasad pisania czystego kodu w C++ Programowanie funkcyjne i obiektowe Wskazówki dotyczące programowania sterowanego testami (Test Driven Development) Wzorce projektowe i idiomy z C++ Praktyczne wykorzystanie wzorców projektowych podczas programowania Czysty kod C++17: elegancja, prostota i moc.
